A negative binomial model with varying element sizes
ICI Fibres Pontypool
Compound Poisson distributions are generally associated with counts of discrete events on sample elements of uniform size. The case of variable element sizes, applicable to many compound distributions, is considered here for the particular case of the negative binomial model. Maximum likelihood and weighted least squares estimators for its parameters are presented, with examples.
